AmyA said:I have been thinking this all along...that the liquid was the horcrux and not the locket.
I also thought this, and said so here: Potion = Horcrux?
We sure do hear a lot about potions vis a vis Snape for him not to have been intimately involved in a potion that's so important to the plot in the last couple chapters.
The only obstacle is that you can't imagine DD would have allowed Harry to navigate the last Horcruxes alone, although there's a lot of indication in this book that DD had more confidence in Harry's abilities...I thought DD was going to die as Harry was forced to pour the liquid down his throat. It was obvious he either knew or suspected he was going to meet his maker very soon.
BTW, did anyone else get a kick out of Snape's mother being named Eileen? In a world of Hermoines and Severuses, that just seemed such a normal sounding name. I laughed out loud when I read it.
